Hi!

I would like to show you my conversion of RF1000 printer.
Some time ago I had RF2000 and bigest issue was hotend.
I broke 2x of original hotend, one of them after 1h of print time so I knew that it is poor quality.

Few days ago I bought RF1000 printer and put new mosquito hotend and titan clone extruder.

Super easy to do:
Things to do was only drill 3x holes in aluminium plate and move it from up to down of tension sensor.
I also make some changes with fan control in firmware - i changed fan to be extruder fan and add extra cables to normal fan.
You can mount titan extruder in place of original one.
I used ptfe tube to connect extruder with hotend but it is cut loose inside aluminium plate to make bed leveling work.

Still have to add blower fan but it should be easy also

Nice conversion. The hotend looks tiny

I had the same extruder in my Ultimaker. The problem with this one is, that the big gear isn't secured with a screw as i remember.
Therefore after some months the plastic deformed and the filament wasn't extruded anymore...
Well at least these are cheap and easy to replace

You can buy clone form aliexpres with two versions.
One has no bearing on motor shaft so shaft is rotating over extruder arm and wear it out.
Second has bearing and this one works for me well.

I made fan duct, i used blower it has quite big power.

And how do your print results are? Better , equal still need tuning? I asume you use 1,75mm now?

I am still testing it but I don't see any difference between original 1.75 and this one in printing quality.
Maybe it should be little better since extruder use gear and for sure it is more precise.
